| Research Abstract |
In this study, we developed analytical methods to elucidate dynamical changing of the pattern of activity in living neuronal network and using the methods, we discovered hysterical effects of living neuronal network on evoked activity. Moreover, the novel technique, which estimates the logic of the neuronal connectivity pattern adapting a fuzzy operator, was established. This is the technique of extracting the regularity and logicalness of a functional connectivity pattern between neurons using T-norm and T-conorm operator. Using the finding about the duration of the stimuli dependent status variation of a living neuronal network, the dynamical clustering analysis technique was established for the culture system, and a program for dynamical-decoding was developed. Furthermore, the small mobile robot was connected to the dissociated culture system as a vehicle for an interaction to the external world. The system with feeds back the input from sensors on the robot body to a culture system was developed. This neuro-robot system is useful as a platform for a substantiation test of the methods of neuronal decoding.
